Understanding the nature of copying errors in the cultural transmission of material culture is highly relevant for students of cultural evolution, especially in the field of evolutionary archaeology. In this paper, we set up a classic transmission chain experiment, which involves making clay anthropomorphic figurines, to explore the nature of the copying error related to the production of 3D objects. The experiment consists of four independent transmission chains, each with 10 participants. Three chains are non-expert chains, as they consist of students of archaeology and psychology with no formal training in arts. The fourth is an expert chain consisting of art students. Our results show that the copying error predictably differs between the experts and the non-experts – it is lower in the expert chain. However, in both groups, the error is higher than predicted by the models that assume that the copying error is only due to imperfections in the perception of linear dimensions. Taken together, these two results suggest that, in addition to the error in perception, the error in the execution contributes significantly to the overall error, as predicted by the recently formulated object-mediated transmission model (Crema et al., 2023). The results of our experiment also show that the errors are often biased rather than random, suggesting that the transmission process involves the transformations anticipated by the cultural attraction theory. •Transmission chain experiment is carried out with clay anthropomorphic figurines.•Copying error of linear dimensions is higher than the Weber fraction (3%).•Art students make less error than other students in copying features of figurines.•Copying errors are often biased, as predicted by the cultural attraction theory.
